The Origin and Early Evolution of Animals

The Ediacara biota (575 - 543 million years old) is a Late Precambrian assemblage of soft-bodied organisms that represent the oldest animals in Earth history. Some species show familar patterns and appear to represent the rootstock from which modern metazoans evolved, others are difficult to classify with any living animal groups and may represent a "failed experiment" in the evolution of life. Ediacaran communities were the first animal ecosystems on Earth, and studies of their interactions with their environment and each other can shed light on the origin of ecosystems. To see images of these fossils these fossils, please visit our on-line exhibits The Mistaken Point assemblage and The Oldest Complex Animals.


Our studies in NW Canada, southern Africa, and Newfoundland over the past two decades resulted in numerous publications and several graduate theses. Recent investigations have increasingly focused on the Mistaken Point biota of eastern Newfoundland (575-560 Ma), which represents the oldest Ediacaran fossils known anywhere, in fact the oldest large and architecturally complex organisms in Earth history. These Ediacaran fossils are preserved on more than 100 large bedding surfaces spanning nearly 4 km of section, each surface littered with tens to thousands of fossil specimens that died in place when they were smothered beneath beds of volcanic ash. This provides a superb natural laboratory for our studies of the affinities, evolution, and ecology of early animals and their ecosystems. Five M.Sc. theses, a Ph.D. thesis, and two post-doctoral fellowships have been completed on the paleobiology and life environments of these critical fossils, and other research projects are available.
